Storage devices are such things as hard drives, CD-Burners, floppy drives, DVD Burners, zip drives, and tape. All these devices store data in different ways.
Hard drives use magnetic drives that store permanent data. They are in mostly every PC you buy today. They hold such things as the operating system, programs, and your files. Hard drives are secondary devices. RAM is a primary storage device. Hard drives must be formatted before use. An operating system that controls hard drives is DOS (Disk Operating System).
CD-Burners and DVD Burners use lights to read and write to plastic discs. This is less clumsy then magnetic drives. The use of CD has become popular because they can hold a good amount of data. Up to 650MB to be exact. DVD-Burns can hold up to 17GB of data. Though the DVD (digital video disk)-Burners are expensive, they’re used primarily to put movies on.
Floppy and Zip drives are work the same way hard drives do. They are magnetic drives. Every PC today must have at least a 3 ½ floppy drive. This device is needed for aide in the installation of operating systems and drives.
Tape drives are primarily used to backup information. This good for making copies of your work incase your hard drive fails. Tape drives are very slow and sometimes expensive to.
